24.

In the 1970's scientists began investigating the chemical reactions that caused the destruction of the ozone in the upper atmosphere. Which statement BEST describes a direct result of their research on society and on the environment?

a)

Global positioning technology was invented. (GPS)

b)

Research on a reusable space shuttle was initiated (started/began).

c)

Alternatives to ozone depleting aerosols were invented.

d)

Plastic bags were invented as an alternative to paper bags.

25.

How might the destruction of the ozone layer be harmful to humans? Ozone, O3, is a molecule of oxygen that makes up the ozone layer. The ozone layer is the part of Earth's atmosphere that prevents most of the Sun's UV (ultraviolet) light from reaching Earth's surface. Certain pollutants, called CFC's (chlorofluorocarbons), have been released into the atmosphere by humans. These pollutants destroy the ozone layer.

a)

Holes in the ozone layer might let in more UV light, which might increase the occurrence of skin cancer.

b)

Holes in the ozone layer might prevent ozone molecules from properly filtering out pollutants in the air, which might increase the occurrence of lung cancer.

c)

Holes in the ozone layer mean there is a decrease in ozone, which is needed for human respiration.

d)

Holes in the ozone layer might let in more heat from space, causing global temperature to increase.
